[Xymon] custom scripts for windows servers

Test.groovy isn't an 8.3 filename but that doesn't seem to matter. If bbwin
had a problem, I would expect something in the log about file not found --
similar to the logfetch message.
Have you checked Task Manager to seee if there a orphanned groovy
processes? The bbwin.log says it started groovy so maybe it's not fully
initializing, can't open the groovy script, etc. I know you said you can
manually run the script so maybe the user/context bbwin runs under doesn't
have permissions to the groovy executable.
Also, may create a simple "hello world" BAT or CMD file and add it as an
external test. This should help prove bbwin can run externals and
hopefully better narrow the problem.
